US President-elect Joe Biden on Monday hailed as cause for “hope” news that a Covid-19 vaccine developed by Pfizer and BioNTech was 90 percent effective, but warned of a long battle ahead.
“I congratulate the brilliant women and men who helped produce this breakthrough and give us cause for hope,” Biden said in a statement, adding that he received advance notice of the announcement Sunday night.
